A Sun Valley construction worker plunged to his death Monday morning when his tractor toppled over a local rock quarry cliff into a pool of water more than 150 feet below.
The man, whose name was not released pending notification of his family, was pushing heavy equipment up a steep, narrow road when the embankment underneath one of his tractor wheels crumbled, the Los Angeles County Fire Department said.
His tractor tumbled over an adjoining cliff into an 18-foot-deep pool of water at the bottom of the quarry, officials said.
By the time a rescue crew reached the man, who was still underwater, he was dead, officials said.
Lt. Mickey Gallagher, a Fire Department lifeguard whose crew was involved in the rescue attempt, said the man probably died before he hit the water.
